Any idea what the tubular material is and what the welds look like?
These are stainless.
These are the inconel ones in the MRC manual, these were ceramic coated white (because racist).
Do you honestly think they made a difference power wise? I had a tubular set of manifolds on my old 2.7t and they definitely helped with spooling being quicker.bam_bam wrote:Those look very tidy, not that I'm an expert on the matter.
The inconel ones were £2600 about 10years back. I got the stainless ones made up for £1600.
I'm really not sure any more. There have been cars that now make good power without the tubulars but there's probably a point where the log-style manifolds become a hinderence to top-end numbers. It's more a question of how much power do you want to make? When chasing numbers I guess you've gotta do everything.Jayjay101 wrote: ↑Sun Feb 17, 2019 9:52 pmDo you honestly think they made a difference power wise?

That is actually a Nickel steel rather than a stainless (even better corrosion resistance). So it will have about the same Chromium as a stainless but it will also have around 11% Nickel.
I got my thermal coating done by a company in Germany called thermo tech
